Worked on file upload functionality at index page

Codereview: http://codereview.appspot.com/4820042/ [PatchSet 2]

Isssues:

i) Asked at codereview itself.

reply:' answered

ii) And after removing that index2 file, should i also remove its link from item-views bar at top(in this current changeset itself).

reply: Yes, it needs completly removed on all places it is called. (hg remove)

iii) Can i commit this now, move towards multiple action functionality, I am thinking to do first multiple downloading thing by selecting each item and after this i will add that content-type-filter and select all thing (OR rather than adding this content-type-filter, i could do this in javascript itself as "Select all images, texts, audios etc" but again this selection will be done on basis of major types).

reply: after the small changes done

Because of the discussion with marchael. It is not necessary to serialize work only in one repository. You can have always more than one where you do different work. If you just pull in each before you commit something you don't have to merge.
